Mosquito Season in Alabama: When to Start for Best Results

Most people call us about mosquitoes in late June, standing in a backyard they've stopped using. By then the population has been doubling on itself since March. Starting earlier isn't a sales pitch — it's the single biggest variable in how well the whole season goes.

When is mosquito season in Alabama?

Alabama mosquito season effectively runs March through November. Mosquitoes become active once temperatures hold consistently above about 50°F, breeding accelerates sharply past 70°F, and activity doesn't meaningfully stop until sustained cold in late fall. That's a nine-month season — considerably longer than most of the country, and the reason our treatment program is built as nine treatments rather than a summer add-on.

Why does starting early matter so much?

Because mosquito populations compound. A single female lays 100 to 300 eggs at a time, and in Alabama's summer heat a mosquito goes from egg to biting adult in about 8 to 10 days. That's a new generation roughly every week and a half, each one larger than the last.

Treat in March or April and you're suppressing a small founding population before it multiplies. Wait until late June and you're fighting six or eight compounded generations — the same treatment, applied to a vastly larger problem, producing a visibly worse result. Same product, same technician, different outcome, purely because of timing.

What mosquito control can and cannot do

Mosquito control means significant, noticeable reduction — not elimination. We want to be straight about that, because it's where a lot of frustration in this industry comes from.

Your yard isn't sealed. Mosquitoes fly in from the neighbor's untreated property, from a drainage ditch down the street, from the creek behind the subdivision. What a well-run program does is knock down the population breeding and resting on your property and keep it suppressed, so the yard becomes usable again. Anyone promising a mosquito-free yard is describing something the biology doesn't support.

How does mosquito barrier treatment work?

Barrier treatment targets the shaded, humid places where adult mosquitoes rest during the day — not the open air. Mosquitoes are poor fliers and spend most of daylight hours motionless on the undersides of leaves, in dense shrubs, under decks, along fence lines, in ivy and monkey grass, and in the shaded strip behind the garage.

A technician treats those resting sites directly, along with breeding sites where standing water can't be eliminated. Products are EPA-registered and applied according to label directions. The treatment continues working on the resting surfaces between visits, which is why the schedule matters more than the intensity of any single application.

Which mosquitoes are in Alabama?

Two groups matter for most homeowners. The Asian tiger mosquito is the black-and-white striped one that bites during the day, breeds in astonishingly small containers, and rarely travels more than a couple hundred yards from where it hatched — which means if it's biting you, it almost certainly hatched on or near your property. That's the good news: it's the most treatable mosquito you have.

Culex mosquitoes bite at dusk and after dark, breed in stagnant water with organic material, and are the group associated with West Nile virus in Alabama. They travel farther, which makes them somewhat harder to control from your yard alone.

Where is standing water hiding in your yard?

Asian tiger mosquitoes can complete their cycle in a bottle cap's worth of water. The usual suspects on Alabama properties:

• Clogged gutters — the single most overlooked breeding site on most homes
• Plant saucers under potted plants, and the plants themselves in bromeliads
• Corrugated downspout extensions, which hold water in every ridge
• Tarps, boat and grill covers, and trampoline pads with sagging low spots
• Children's toys, wheelbarrows, buckets, and upturned trash can lids
• Tree holes, French drain outlets, and low spots that hold water for a week after rain
• Pet bowls and bird baths that aren't dumped and refilled at least weekly

Walking the yard after a rain and dumping everything that holds water is genuinely the highest-value free thing you can do. It also multiplies the effect of treatment, because you've removed the nursery rather than just the adults.

What does mosquito service cost in Alabama?

Our mosquito program runs about $45 per treatment across nine treatments, March through November — roughly $33.75 a month when spread evenly across the year. Adding tick and chigger coverage brings it to about $65 per treatment, or roughly $48.75 a month.

Both are their own services rather than part of the bi-monthly pest plan, because mosquito work uses different products, different equipment, and a different treatment map than interior and perimeter pest control.

Common questions

How long does a mosquito treatment last? Treatments are scheduled roughly every three weeks through the season, which is set to the mosquito life cycle rather than the calendar. Heavy rain shortly after an application can reduce residual, and if that happens we'll come back out.

Do those citronella candles and yard sprays work? They create small, brief effects near the source. They don't reduce the breeding population, so nothing carries over to tomorrow. That's the core difference between repelling and controlling.

Do mosquito misting systems work better? They apply more often, but they apply on a timer rather than to the resting sites that matter, and they don't address breeding. We'd rather treat the right places on the right schedule.

Is it too late to start in July? No — it just means the first couple of treatments are working harder against a bigger population. Most families see a clear difference within two to three visits.
